Or, Waterloo even! Although I think KX StP probably takes the prize:
St P International
HS1 Suburban
Thameslink
MML
KX Mainline
KX Suburban
Circle
H&C
Metropolitan
Northern
Picadilly
Victoria

I would go with Waterloo
Waterloo Main
Waterloo East (trains to and from Charing Cross)
Northern
Bakerloo
Jubilee
W&C

Compared with the southern TOCs, at Waterloo and at Charing Cross, the
terminal platforms at St Pancras (all three parts) and Kings Cross are
practically quiet rural stations. Charing Cross dispatches just about as
many trains in an hour from 6 platforms as Kings Cross and St Pancras
(except LL) combined do from 22 (or is it 23 now?), and Waterloo, with
slightly fewer non-theatre platforms than KXStP, dispatches twice as many.
